Hi everyone, I need to replace the euro cylinder lock on my front door but for the life of me I can't seem to find a replacement lock that will fit! I've attached pics for my lock + the measurements. It's the first time I'm doing this so naturally I have no experience whatsoever. The size of this lock appears to be around 83mm total... but I can't find any locks that are this size. I have tried 35/50mm locks, 35/45 etc but none of them works! Where am I going wrong with this please? Any advice would be greatly appreciated.
